Cleveland Oak has the capability to bond friction material to large clutch plates (up to 116″ diameter) and does so on a regular basis. This case, however, presented special challenges, not the least of which was that the new customer’s spare plate (from another vendor) had failed and they were in a breakdown situation.

The 116″ diameter plate required special lining as well has being of very large diameter. The lining consisted of 40 segmented trapezoids with rounded corners, which normally would not be an issue except that these were 1.5″ thick and required bolting to the plate as well as bonding. The counter-bored bolt holes were to be plugged with lining. Because of time restraints the friction lining had to be laminated to build the required thickness, then cut to final size on the water jet saw.

The job actually went smoother than expected and the relined plate was shipped 8 days after receipt of the order. The 12,000 ton forging press is up and running. Since then we have also relined the spare plate, albeit in a more leisurely manner.

Our capability, coupled with commitment to customer requirements, product knowledge and ability to innovate came together to complete this challenging project. Contact us to see what we can do for you.
